Method and apparatus for delivering data unit based on execution time indicator in wireless communication system

Abstract

The present invention relates to a method of receiving a data unit by a wireless node in a wireless communication system. In particular, the method includes the steps of: receiving, from a lower layer, a data unit including an execution time indicator; deciphering the data unit; and delivering, to an upper layer, the data unit at a predefined execution time without re-ordering.

1 . A method for receiving a data unit by a wireless node in a wireless communication system, the method comprising:
 receiving, from a lower layer, a data unit including an execution time indicator;   deciphering the data unit; and   delivering, to an upper layer, the data unit at a predefined execution time without re-ordering.   
     
     
         2 . The method of  claim 1 , further comprising performing integrity verification to the data unit. 
     
     
         3 . The method of  claim 2 , wherein the data unit is delivered to the upper layer after performing header decompression. 
     
     
         4 . The method of  claim 1 , wherein information about a predefined execution time included in the data unit. 
     
     
         5 . The method of  claim 4 , wherein the execution time indicator indicates whether Information about predefined execution time included in the data unit or not. 
     
     
         6 . A wireless node in a wireless communication system, the wireless node comprising:
 a memory; and   at least one processor coupled to the memory,   wherein the at least one processor is configured to:   receive, from a lower layer, a data unit including an execution time indicator;   decipher the data unit; and   deliver, to an upper layer, the data unit at a predefined execution time without re-ordering.   
     
     
         7 . The wireless node of  claim 6 , wherein the at least one processor is configured to perform integrity verification to the data unit. 
     
     
         8 . The wireless node of  claim 7 , wherein the data unit is delivered to the upper layer after performing header decompression. 
     
     
         9 . The wireless node of  claim 6 , wherein information about a predefined execution time included in the data unit. 
     
     
         10 . The wireless node of  claim 9 , wherein the execution time indicator indicates whether Information about predefined execution time included in the data unit or not. 
     
     
         11 . The wireless node of  claim 6 , wherein the at least one processor is further configured to implement at least one advanced driver assistance system (ADAS) function based on signals that control the wireless node.
